A) Brownian movement
B) cataphoresis
C) Tyndall effect
D) none of the above
Correct Answer: B
Solution :
Particles having size between 1-100 nm are called colloids. Colloidal particle in the dispersion medium develops charge so they move to the oppositely charged electrodes under the effect of electric current. This is called electrophoresis or cataphoresis. The zig zag movement of colloidal particles is called Brownian movement. The scattering of light when it passes through a colloidal solution is called Tyndall effect.
